Explanation:

When independent sentences are connected by any of the following seven coordinating conjunctions, use commas to separate them: and, but, for, or, nor, so, yet.

After introductory a) sentences, b) phrases, or c) words that precede the main clause, use commas.

In the midst of a statement, use a pair of commas to denote clauses, phrases, and words that are not necessary for the sentence's meaning. Use one comma before and one after the pause to mark the start and end of the pause, respectively.
